BACKGROUND OF THE INVENTION

1. Technical Field of the Invention

The present invention relates to modified DFR nucleic acids and encoding the modified DFR that preferentially utilize DHK as a substrate and their uses for genetically altering plants to increase the content of pelargonidin-based pigments in the plants.

2. Description of the Prior Art

Anthocyanins are classes of pigments that determine flower color and plant pigmentation in angiosperm plants. Among anthocyanins, pelargonidin-based pigments confer bric-red/orange color to plants, while cyanidin- and delphinidin-based pigments confer red and violet color each (Holton, et al. Plant Cell 7:1071-1083 (1995); Tanaka, et al. Plant Cell Physiol. 39:1119-1126 (1998)). Different ratio of these pigments confers a wide range of flower color. Many anthocyanin bio synthetic genes have been identified. One of key enzyme in the biosynthetic pathway is dihydroflavonol 4-reductase (DFR). The enzyme converts dihydroflavonols (dihydrokaempferol (DHK), dihydroquercetin (DHQ), and dihydromyricetin (DHM)) to leucocyanidins. The leucocyanidins are subsequently converted to anthocyanins by other enzymes. The conversion of DHK to DHQ and DHM are catalyzed by flavonoid 3′-hydroxylase (F3′H) and flavonoid 3′,5′-hydroxylase (F3′5′H) Since DFRs in most plants can convert all three dihydroflavonols to leucocyanidins, the ratio of three classes of anthocyanin pigments are mainly determined by the activity of F3′H and F3′5′H (Holton, et al. Plant Cell 7:1071-1083 (1995)).

Since pelargonidin-based pigments confer the orange color to flowers, the F3′H and F3′5′H activities must be absent for a plant to have orange colored flowers (U.S. Pat. No. 5,410,096). In many plant species, F3′H and F3′5′H are encoded by a multiple genes, thus the mutant lines that lack F3′H and F3′5′H are not easily found. This partially accounts for the rarity of orange-colored flowers in some plant species. Inability to reduce DHK to leucocyanidin by DFR in some species can also cause the lack of orange-colored flower. For example, DFRs from Petunia and Cymbidium convert DHK to its leucocyanidin very inefficiently, thus these species do not accumulate large ratio of pelargonidin-based anthocyanins even if F3′H and F3′5′H are absent (Gerats, et al. Planta 155:364-368 (1982); Johnson, et al. Plant J. 19:81-85 (1999)). An orange-colored Petunia was engineered by introducing a maize DFR to a special mutant line of Petunia that lacks F3′H and F3′5′H (Meyer, et al. Nature 330:677-678 (1987)). Since the maize DFR can convert all three dihydroflavonols to their leucocyanidins, such a mutant line that accumulates DHK was necessary for the development of orange-colored Petunia. The necessity of the special mutant line can be circumvented by using a DFR that utilizes DHK preferentially over DHQ and DHM.

Using chimeric DFRs between Petunia and Gerbera DFRs, we identified a region that determines the substrate specificity of DFR. By altering an amino acid in the region, we developed a DHK-specific DFR that converts DHK preferentially over DHQ and DHM. When expressed in plants, the DHK-specific DFR increases the pelargonidin-based pigments regardless of F3′H activity.

SUMMARY OF THE INVENTION

FIG. 1A is a schematic diagram showing three chimeric DFRs. Black bars indicate sequences from a Gerbera DFR and gray bars indicates sequences from a Petunia DFR. Numbers are junctional amino acid positions from the translation start site of the Gerbera DFR. C.1, C.2, C.3 are the name of three different chimeric DFRs.

FIG. 1B shows representative flowers of transgenic Petunia expressing chimera DFRs or control DFR. Ger indicate the transgenic flower expressing Gerbera DFR and C.1, C.2, and C.3 indicate Chimera 1, Chimera 2, and Chimera 3 each. RL01 line has a functional Petunia DFR gene. The C.1 and RL01 bore similar pink colored flowers while others bore bric-red colored flower. The transgenic W80 flower expressing C.1 has pink color, while transgenic W80 flowers expressing C.2 and C.3 have orange/bric-red color. The orange/bric-red color can be also observed in the transgenic Petunia flowers expressing the native Gerbera DFR.

FIG. 1C shows the TLC analysis data of pigments produced in transgenic Petunia flowers next to standard pigments (pelargonidin (Pg), cyanidin (Cy), and delphinidin (Dp)). The transgenic flowers expressing C.1 has mainly cyanidin- and delphinidin-based pigments, while the flowers expressing C.2 and C.3 have mainly pelargonidin-based pigments in addition to small amount of cyanidin- and delphinidin-based pigments.

FIG. 2 shows the amino acid sequence of Gerbera DFR aligned with other representative DFR sequences. The ClustalW program was used to align multiple amino acid sequences (Thomson, et al. Nucl. Acids Res. 22:4673-4680 (1994)). The substrate specificity determining region is boxed and the 134h amino acid residue of Gerbera DFR and coressponding amino acid residues of DFRs from a few representative species are bold typed.

Ger indicates the wild type Gerbera DFR and T132V indicates the mutated DFR that has valine instead of threonine at the 132th position of Gerbera DFR. Names of other mutated DFRs followed the same notation rule. All transgenic lines except N134L and E145L have the same bric red colored flower. The N134L bore slightly different colored flowers and E145L bore white flowers.

FIG. 3C shows a TLC analysis of pigments produced in the transgenic Petunia flowers. As expected, the E145L did not accumulated any anthocyanin. The N134L accumulated mostly pelargonidin while other mutated DFR and wild type Gebera DFR accumulated significant amount of cyanidin and delphinidin in addition to perlargonidin.

The mark—indicates no DFR gene, DFR^(N134L) indicates DFR that has leucine instead of aspargine at the 134^(th) position of Gerbera DFR, and DFR^(WT) indicates the wild type Gerbera DFR. The flower located in the cross section indicate the WR or WV transgenic flowers expressing DFR^(N134L) or DFR^(WT).

FIG. 4B shows a TLC analysis of pigments produced in the transgenic lines. Pg, Cy, and Dp indicate pelargonidin, cyanidin, and delphinidin. The WR and WV lines expressing wild type DFR accumulated cyanidin and delphinidin each. The WR line expressing DFR^(N134L) accumulated pelargonidin and cyanidin, while the WV line expressing DFR^(N134L) did not accumulated any pigment other than background level of delphinidin.

DETAILED DESCRIPTION OF THE INVENTION

In accordance with the present invention, the substrate specificity determining region was identified by determining the abilities of three chimeric DFRs to catalyze the reduction of DHK in the transgenic Petunia lines. In order to identify the region of DFR that determines its substrate specificity, we constructed chimeric DFR genes using cDNA sequences of Petunia (SEQ ID NO: 35) and Gerbera (SEQ ID NO; 1). Though these two DFRs have high similarity at the amino acid level, Gerbera DFR is able to catalyze dihydrokaempferol (DHK) while Petunia DFR cannot (Elomaa et al. Mol. Gen. Genet. 248:649-656 (1995)). We built three different chimeric genes using regions of high homology as common PCR primer sites (FIG. 1A). The chimeric genes were transformed into a white flowered Petunia mutant (W80) that lacks DFR activity and accumulates primarily DHK but with appreciable amounts of dihydroquercetin (DHQ) and dihydromyricetin (DHM) (Huits et at, 1994). Chimera 1 produced pink flowers while Chimeras 2 and 3 bore orange-pink flowers (FIG. 1B). The hue of Chimera 1 flowers is very similar to the inbred Petunia mutant RLO1, which has functional DFR activity and accumulates DHK. Thin layer chromatography (TLC) determined that Chimera 1 produced mainly cyanidin and delphinidin (FIG. 1b). Chimeras 2 and 3 primarily produced pelargonidin (FIG. 1C), which is the downstream product of DFR reduction of DHK. These results indicated that the region of DFR conferring the ability to reduce DHK was between Chimeras 1 and 2. The identified region (approx. 40 amino acids) is highly variable in DFRs from different plant species. By excluding the completely conserved amino acid sequences at the borders, the identified region is narrowed down to 26 amino acids. Hereinafter, this region is referred as substrate specificity determining region. An example of the substrate specificity determining region in a few representative DFRs is shown in FIG. 2.

The invention provides the modified DFR nucleic acids and encoded DFRs that have altered amino acid sequences at the substrate specificity determining region. Such DFRs have properties characterized by the altered substrate specificity. Hereinafter, DFRs that catalyze the reduction of one substrate preferentially over other two substrates are referred as substrate-specific DFRs. In the preferred embodiments, the invention provides the modified DFR that has altered amino acid at 134^(th) amino acid residue of Gerbera DFR or the corresponding amino acid residues of DFRs from other species. Such DFRs have properties characterized by catalyzing the reduction of DHK preferentially over DHQ and DHM. Hereinafter, DFRs that catalyze the reduction of DHK preferentially over DHQ and DHM are referred as DHK-specific DFRs. The 134^(th) amino acid residue of Gerbera DFR and corresponding amino acid residues of DFRs from a few representative species are shown in FIG. 2.

In accordance with the present invention, a DHK-specific DFR was developed by replacing asparagine at 134^(th) amino acid residue of Gerbera DFR to leucine. The expression of the DHK-specific DFR in W80 Petunia line, which accumulates large amount of DHK in addition to appreciable amount of DHQ and DHM, caused the production of only pelargonidin. The expression of native Gerbera DFR in the same Petunia line caused the production of appreciable amounts of cyanidin and delphinidin in addition to pelargonidin (FIG. 3). Since the W80 Petunia line we transformed accumulates mainly DHK with small amount of DHQ and DHM, it was not clear if the N134L mutant DFR completely lost the capability of reducing DHQ and DHM. To investigate if the N134L mutant DFR produces only pelargonidin in the presence of fully active flavonoid-3′-hydroxylase (F3′H) or flavonoid-3′,5′-hydroxylase (F3′5′H), we crossed our N134L transformant with Petunia lines that are either dfr^(−/−)/F3′H^(+/+) (WR line) or dfr^(−/−)/F3′5′H^(+/+) (WV line). As shown in FIG. 4A, both WR and WV lines bore white flowers as expected. When these lines were crossed with the N134L transformants, the WR line expressing the mutant DFR (WR/DFR^(N134L)) had orange colored flowers while the WR expressing wild type Gerbera DFR (WR/DFR^(WT)) had red colored flowers. Unlike the WR lines, the WV lines expressing the mutant DFR (WV/DFR^(N134L)) bore white flowers while WV lines expressing the wild type DFR (WV/DFR^(WT)) had violet colored flowers. To determine the pigments produced in these crossed lines, we performed TLC analysis. FIG. 4B shows that the WR/DFR^(N134L) accumulated a large amount of pelargonidin while WR/DFR^(WT) mainly accumulated cyanidin. In the white flowered WV/DFR^(N134L), no appreciable amounts of anthocyanidins accumulated other than a background level of delphinidin. In contrast to WV/DFR^(N134L), the WV/DFR^(WT) accumulated mainly delphinidin. The data indicate that the N134L mutant DFR preferentially utilizes DHK as a substrate over DHQ and cannot reduce DHM. The substrate preference of the N134L mutant DFR is somewhat opposite to that of Petunia DFR which prefer DHM over DHQ and cannot use DHK (Forkmann and Ruhnau, 1987). The results indicates that the DHK-specific DFR can increase the pelargonidin-based pigments in plants regardless of the presence of F3′H activity.

The invention also provides plants having cells transformed with vectors comprising at least a portion of the substrate-specific DFR nucleic acids. Such plants have phenotypes characterized by the increased content of anthocyanins specified by the substrate specific DFRs. In the preferred embodiments, the invention provides plants having cells transformed with vectors comprising at least a portion of the DHK-specific DFR nucleic acids. Such plants have phenotypes characterized by the increased content of pelargonidin-based pigments.

The following is presented as examples and is not to be construed as a limitation on the scope of the invention.

EXAMPLE

Petunia Transformation

Leaf explants of the inbred Petunia W80 line (an6⁻, ht1⁻, ht2⁻, hf1⁻, hf2⁻, fl⁻, and rt⁻) were transformed as described elsewhere except that leaf explants recently infected by Agrobacterium tumefaciens were rinsed with Murashige-Skoog solution containing 750 mg/L cefotaxime and then placed on media having 100 mg/L kanamycin sulfate and 500 mg/L cefotaxime (Johnson, et al. Plant J. 19:81-85 (1999)). Also, putative transformants were grown on MS media with vitamins, 30 g/L sucrose, 0.6% agar and 500 mg/L cefotaxime; after rooting the transformants were transferred to soil.

Chimeric Gene Construction

Highly conserved regions of the DFR gene were identified by a multiple sequence alignment of a number of DFRs. The 5′ region (Gerbera DFR Portion) of each chimeric gene was synthesized from the Gerbera DFR cDNA clone using a primer containing the codon for the starting methionine of the Gerbera DFR gene SEQ ID NO. 5): 5′-GGC GAA AAT GGA AGA GGA TTC TCC-3′ and a primer containing a conserved region of the Gerbera DFR gene (Chimera 1; SEQ ID NO: 6: 5′-AGC AGA TGA AGT GAA CAC TAG TTT TGA CAC GAA-3′; Chimera 2; SEQ ID NO 7: 5′-GGC TTT CTC TGC CAG AGT TTT TGA CAC GAA-3′; Chimera 3; SEQ ID NO 8: 5′-GTG GGA CGA GCA AAT GTA TCT TCC TTT TGC-3′). The 3′ region (Petunia DFR portion) of each chimeric gene was synthesized from the Petunia DFRA cDNA clone using a primer complementary to the three conserved regions (Chimera 1; SEQ ID NO: 9: 5′-TTC ACT TCA TCT GCT GGA ACT CTC GAT GTG; Chimera 2; SEQ ID NO: 10: 5′-CTG GCA GAG AAA GCC GCA ATG GAA GAA GCT-3′; Chimera 3; SEQ ID NO: 11: 5′-ATT TGC TCG TCC CAC CAT GCT ATC ATC TAC-3′) and a primer containing the stop codon of the Petunia DFRA gene (SEQ ID NO; 12); 5′-GCG CTA GAC TTC AAC ATT GCT TAA-3′. 5′ and 3 regions were gel purified after PCR amplificaftion. To assemble the full length chimeric gene the 5′ and 3′ region fragments were added to the same tube in roughly equal amounts and subjected to PCR cycles (94°C. 30″, 55° C. 30″, 72° C. 1 :30). Full-length chimeric genes (−1.1 kb) were purified from agarose gels. The chimeric genes were cloned into a vector containing the 35S CaMV promoter and NOS terminator. Pfu polymerase (Stratagene, La Jolla, Calif.) was used for all PCR reactions.

Amino Acid Point Mutant Construction

Gerbera DFR genes containing one amino acid point mutation were made in a similar manner as the chimeric genes. The 5′ region was synthesized using a primer having the Gerbera DFR starting methionine and a primer containing a single codon change. The 3′ region was made with a complementary primer with the single codon change and a primer having the stop codon of Gerbera DFR. The full length mutant sequence was assembled like the chimeric genes above. Each point mutant was cloned into a vector having the 35S CaMV promoter and NOS terminator. The mutagenized region of each mutant DFR was sequenced to ensure the correct residue was changed. Point mutants were then transformed into the W80 Petunia line. The transformants expressing the DFR genes were crossed with WR Petunia line (dfr^(−/−), F3′H^(+/+)) and WV Petunia line (dfr^(−/−), F3′5′H^(+/+)) to determine the substrate specificity of the mutated DFR. Mutations in other loci were not determined in these two Petunia lines.

TLC Analysis

Anthocyanidins were separated on cellulose TLC plates as described (Johnson, et al. Plant J. 19:81-85 (1999)). Corollas were sometimes stored at 4° C. for extended periods of time in methanol-0.5% HCl solution. Before adding iso-amylalcohol, the flower extracts were quantified at 530 nm to ensure uniform loading on the TLC plate. Anthocyanin standards were purchased from Apin Chemicals Ltd. (Oxfordshire, England).

Sequence Alignment

Multiple sequence alignment of DFRs was done using ClustalW program.
